2 Claims.

The present invention relates to an improved snow plow and scraper, andaims to provide a construction having substantial rigidity to withstandthe rough usage encountered by articles of this character and which maybe easily manually operated.

Another object of the invention is to provide a construction which maybe adjusted to perform the function of either a scraper or a pathclearer.

Another object ci the invention is to provide a construction of thischaracter which may be stored or shipped in a collapsed condition andreadily opened up for usetas occasion requires.

An additional object of the invention is to provide a wheel or rollersupporting means ior the scraper or plow which substantially adds to thefacility with which the device may be utilized.

An important feature oi the invention resides in fixedly supporting thewheel or roller in a manner which allows the construction to becollapsed without the wheel constituting an obstruction. Also, theroller` supporting means forms a part of the means for allowing the plowto be adjusted for purposes of a scraper or a path clearer.

Referring to the drawings:

Figure 1 is a rear view in perspective oi" the plow with the handle barpartly broken away, and showing the device arranged to clear a path,

Figure 2 is a front perspective view showing the plow similarly arrangedto clear a path,

Figure 3 is a sectional view showing the wheel or roller mounting on thehandle, and

Figure 4 is a front perspective view of the plow arranged as a scraper.

In Figures l and 2 a bar I0 carries at its lower end an integralvertically extending wing support or pintle I I. In some cases thepintle I I is welded to the end or the bar It. It will be noted that thebar I extends laterally with respect to the pintle and in asubstantially horizontal relation thereto. Hingedly or pivotally carriedby the pintle ll are the wings I2 and I3 of the plow or scraper. Eachwing carries upper and lower strap iron hinge members It and I5 whichare secured to the wings, as shown by means of bolts I6, and the curledpintle receiving portions Il of the strap members Ifl are so disposedand received on the wing support II that a pair on one wing, forexample, the wing I3, is disposed between the other or outer pair ofcurled pintle receiving portions i3 of the other wing I4 whereby thewings are held on the vertical pintle Without -danger of displacement,and yet have free swinging movement for adjustment to operative posi-Chicago, Ill., assigner to Mare- Ill.,

tion or Jfor collapsing the wings when storing or shipping the plow.

The wings are provided with outwardly bent portions I9 and 20, the lowerportions I9 constituting scraper plates and the upper portions 20constituting guards to prevent the snow from creeping over the wings. i

Each of the wings intermediate its body portion and more nearly adjacentthe lower edge is provided with a bracket 2| having an opening 22, andthe bar I0 is provided remote from the pintle il with a bracket 23extending on opposite sides of the handle to which it is bolted orwelded. spaced openings 24 are provided on each side of the bracket 23.

The bar I0 at substantially the juncture J of its horizontally extendingportion I0 and its integral upwardly bent handle pcrtion Ill, e. g., atthe lower end of this latter portion, is provided with an opening 25, asshown in Figure 3, through which extends a shaft 26. One end of theshaft is curled into a hook or opening 21 longitudinally spaced on thebar Ill from the bracket 23 and the opposite end 28 forms a bearing orsupport for the wheel or roller 29. The roller 29 is received on theshaft 28, as shown in Figure 3, and preferably has a ball bearingmounting 30. The roller is supported for rotating movement uponengagement with the ground by the construction described, and is heldXedly in position by reason of the loop or hook 2'I constituting a stopon one end of the shaft, and the nut 3| engaging the opposite threadedend 32 oi the shaft. A washer 33 is included between the nut 3l and thehub of the wheel, and also between the bar I0 and the adjacent hubportion, as shown in Figure 3.

A pair of link members or rods 35 are provided, as shown in Figure 1,and one link member has one end engaged in the opening 22 of bracket 2|on the wing I2 and the other end engaged in the loop 21 of the shaft 26.The other link member, which is relatively shorter, has one end engagedin the opening 24 of the bracket 23 on the bar, and the other endengaged in the opening 22 of the bracket on the wing I3. The arrangementshown in Figure 1 of the relatively longer and shorter links may bereversed, i. e., with the longer link engaging the bracket on the wingI3, and the shorter link engaging the bracket on the wing I2, accordingto whether it is desired to adjust the angular relation of the wings inone direction or the other in clearing a path.

In Figure 4 I have shown the invention adjusted to act as a scraper withthe wings in straight line relation, and in this construction both ofthe links 35 have one end engaged in the opening of a bracket of therespective wings, and their other ends engaged in the openings 24 ofAthe bracket 23 on the bar l0.

It will be observed that to collapse the construction, it is onlynecessary to remove one end of each link from engagement with one of theopenings on the wing or the bar Ill, and the construction may be readilyopened-up for operation by simply having the links engage in therespective openings, as described in connection with Figures 1 and 4.When collapsed, the wings fold against the bar I and the wheel 2 9 thusbecomes lined up with folded wings so that a fiat article is presented.

The plow is preferably constructed entirely of metal, and possesses thenecessary rigidity to assure a long life. It is preferred to employ theroller 29, although in some cases, it may be substituted by a runner, orentirely eliminated.

The bar l0 supports all of the parts of the construction and at its freeend is provided with suitable handle grips 38. If desired, the plow maybe attached to a vehicle or operated by a prime mover.

Referring to Figure 2, it is to be noted that there is an opening Obetween the ends 39 of the outwardly bent bottom scraper portions I9when the plow is used to clear a path. Such opening is notobjectionable, but there are some cases where it is desirable to closethe same. Various means may be used to close this opening.

I claim:

1. A kSnow plow or scraper comprising a bar, wings pivotally mounted onsaid bar, means con necting the wings to the bar at a point remote fromthe pivotal mounting, said connecting on said support.

2,. A snow plow or scraper comprising a bar, wings pivotally mounted onsaid bar, means connecting the wings to the bar at a point remote fromthe pivotal mounting, said connecting carried on said support anddisposed in line with the folded relation of the wings whereby when theplow or scraper is collapsed with the wings in folded position a atarticle is obtained.
